FLUORESCENT LAMPS
FLUORESCENT LAMPS83. The fluorescent lamp (Standard Handbook for Electrical Engineers) is a low-pressure mercury electric-discharge lamp in which a phosphor coating transforms the ultraviolet energy generated by the discharge arc into light. The major parts of a fluorescent lamp (hot-cathode type) are the bulb (tube), electrodes, fill gas, phosphor coating, and bases, as shown in Fig. 10.38. When the proper voltage is applied across the ends of the lamp, an arc is produced by current flowing between the electrodes through the fill gas (mercury vapor mixed with argon or other inert gas). This discharge generates some visible radiation, but mostly ultraviolet at 25…
